Patchset fixed restart of clvmd with -E option.
1st. Adds support for easier restart of clvmd
(i.e. -Isinglenode is preserved).2nd. Bug fixes support of -E arg.
ack these two.
(maybe cluster lock type is on of the attribute we can store in udev db? to read it later :-)

3rd. Allows to build test suite script for checking clvmd restart.
(Any better idea here ?)We need something for testsuite but I would like to avoid any online reconfiguration of daemon paths, this is tricky and bug there is security problem (clvms -S must not start arbitrary program
- it run with root privileges.)
Note - setting (LVM_CLVMD_BINARY as was suggest by agk) must be done before executing the first clvmd.
You can't influence anything by any further clvmd -S call - since this environment is not passed to the original restarting daemons.
Thus it should not introduce security risk here - as you are working only with settings you've had with the first start.
(If someone could manipulate root's environment - he could surely replace disc content as well)
